VIBRATIONAL CHARACTERISTICS OF SOLIDPROPELLANT ROCKET ENGINES

Abstract

An experimental program is described in which the bending and longitudinal dynamics of structures simulating solid-propellant rocket motors are being studied. The structure is considered to be a cylindrical grain of solid propellant to which is bonded a thin steel case. Vibrations of the empty steel cylinder suspended in a free-free condition are studied first. Secondly, a similar steel cylinder loaded with an inert propellant grain will be studied to determine the effect of the propellant on the vibrations of the case. Additional experiments to determine the viscoelastic properties of the propellant required for an analysis of the structure are discussed.
